Arguments

min_age

An integer scalar, minimum age in the model.

max_age

An integer scalar, maximum age in the model.

age_increase_M

An integer scalar, age at which mortality begins to increase.

m0

A numeric scalar, natural mortality at age 0.

m4

A numeric scalar, natural mortality at age 4.

m10

A numeric scalar, natural mortality at age 10.

m30

A numeric scalar, natural mortality at age 30.

Value

A numeric vector of length n_age, natural mortality-at-age.

Legacy status

These functions reproduce historical version-1 assessment code for audit and comparison. They are not the production SBT objective, do not implement the current data, mortality, harvest-wall, or biological-state contracts, and receive only compatibility maintenance. New analyses should use get_data(), sbt_model(), and the current component helpers.
